We almost paid double the price. They added extra insurance and refueling services that we didn't need. Luckily, we checked the bill before going through security and noticed the amount was far off from our reservation. Since RentACar website had no consultation option, we went to the counter and explained the situation. The staff was helpful and canceled the extra charges. We were fortunate! The counter service advised us to always check our contract before taking the car. We couldn't relax for a moment; if we had noticed this back in our country, it would have been impossible to resolve.
